CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to DE 10 2014 205 106.1 filed Mar. 19,2014, the entire disclosure of which is incorporated by referenceherein.

TECHNICAL FIELD

The disclosure herein relates to a sleeping box which is intended forinstallation in an aircraft, and also to a sleeping box arrangementwhich comprises a plurality of such sleeping boxes. The disclosureherein also relates to an aircraft area which is equipped with such asleeping box and/or such a sleeping box arrangement.

BACKGROUND

A passenger cabin of a modern commercial aircraft is normally equippedonly in first class or business class with seats which can be broughtinto a horizontal position and thereby enable the passengers to sleep ina comfortable position. However these seats require a lot ofinstallation space. Seats which are set up in economy class, on theother hand, are very economical on installation space, but the backrestsof these seats are only movable to a limited extent and therefore can befound by the passengers to be uncomfortable, particularly on long-haulflights.

From EP 0 035 955 A2, it is known practice to configure a freightcontainer, which is intended to be transported in a freight compartmentof an aircraft, as a sleeping cabin with a bed. The freight container islifted via a freight hatch into the freight compartment and is movedwithin the latter, via roller tracks provided in the floor of thefreight compartment, to its station, where it is anchored in adetachable manner. Safety belts are associated with the bed in order tooffer users of the sleeping cabin sufficient seating safety when theaircraft takes off and lands. In order to get to the sleeping cabins,passengers are obliged to leave a passenger compartment of the aircraftwhich is fitted with seats, and pass into the freight compartmentthrough a bulkhead provided in a wall that separates the passengercompartment from the freight compartment.

FR 2 903 663 B1 or U.S. Pat. No. 7,699,264 B2 discloses a sleepingmodule which serves as a rest compartment for the crew of an aircraftand comprises two rows of three sleeping boxes each, arranged one aboveanother, and which is intended for installation in a tail area of theaircraft which is accessible from a passenger cabin.

SUMMARY

An object of the disclosure herein is to make available a sleeping boxwhich improves passenger comfort on board a commercial aircraft and isefficient in terms of installation space, as well as a sleeping boxarrangement which comprises a plurality of such sleeping boxes. Afurther object of the disclosure herein is also to indicate an aircraftarea which is equipped with a sleeping box and/or such a sleeping boxarrangement.

These and other objects are achieved, at least in part or whole, by asleeping box having the features disclosed herein.

A sleeping box which is suitable for installation in an aircraftcomprises a casing which is suitable for accommodating a person locatedin a reclining position parallel to a longitudinal axis of the casing.The casing has an access aperture in the area of a front side whichextends perpendicularly to the longitudinal axis of the casing. Ifdesired, the access aperture may be closable by a door. However thecasing is preferably not provided with an access aperture that can beclosed off. The access aperture may extend over the entire front side ofthe casing. As an alternative to this, however, the access aperture mayalso take up only a section of the front side of the casing. What isessential, however, is that the access aperture is sufficiently large topermit a person access into the interior space of the sleeping box, orto allow a person to move out of the interior space of the sleeping boxagain.

The sleeping box also comprises a fastening apparatus which isconfigured to fasten the sleeping box within a passenger cabin of theaircraft in such a way that the longitudinal axis of the casing extendsperpendicularly to a longitudinal axis of the passenger cabin and theaccess aperture of the casing borders on an aisle which is present inthe passenger cabin. The fastening apparatus consequently positions thesleeping box within the passenger cabin of the aircraft in such a waythat a person who is accommodated in the sleeping box liesperpendicularly to the direction of flight of the aircraft and isconsequently pressed flat against a side wall of the casing of thesleeping box in the event of a crash or other action. It is therebypossible to achieve a favorable distribution of the loads acting uponthe person's body, as a result of which the risk of injury to the personis reduced.

The geometry of the sleeping box is preferably designed in such a waythat the passenger only has the possibility of lying in the sleeping boxperpendicularly to the direction of flight of the aircraft. It is thusensured, by suitable configuration of the cross-section of the sleepingbox, that the passenger is lying stretched out perpendicularly to thedirection of flight of the aircraft in the event of a crash or otheraction.

The sleeping box can consequently be installed in the passenger cabin ofthe aircraft by the fastening apparatus in such a way that it can beoccupied even during the taxiing, takeoff and landing of the aircraft.It is thereby possible to dispense with making an additional seatavailable, in the passenger cabin of the aircraft, for a passenger whois occupying the sleeping box. Also, passengers are not obliged, as inthe solutions which are known from the prior art, to leave the passengercabin in order to get to the sleeping box. The sleeping box consequentlyprovides a possibility, which makes particularly efficient use of theinstallation space which is available only to a very limited extent inthe passenger cabin of an aircraft, of accommodating a passenger in acomfortable manner. Because of the efficient design of the sleeping boxin terms of installation space, it is possible to offer, at acomparatively low price, a place in the sleeping box which offers apassenger a high degree of comfort and privacy, it being possible toinstall the sleeping box in the business class or economy class of thepassenger cabin, as required. In addition, the sleeping box isparticularly conveniently accessible to the passengers because of theconfiguration of its fastening apparatus which permits the mounting ofthe sleeping box in the passenger cabin of the aircraft such that theaccess aperture of the casing borders on an aisle.

The fastening apparatus of the sleeping box may be configured to fastenthe sleeping box within a seat rail provided in a floor of the passengercabin. For this purpose, the fastening apparatus may have, for example,a quick-action fastener which can be engaged in a latching manner withinthe seat rail. The sleeping box can then be installed particularlyquickly and easily at a desired position in the passenger cabin. Thesleeping box can also be repositioned in a simple manner in the courseof a reconfiguration of the passenger cabin. Finally, a fasteningapparatus which is configured to interact with a seat rail which ispresent, in any case, in the floor of the passenger cabin, makes itpossible to dispense with an additional fastening apparatus on theaircraft.

In addition, or as an alternative, to this, the fastening apparatus maybe configured to fasten the sleeping box to a further sleeping box suchthat a floor of the casing of the sleeping box borders on a ceiling ofthe casing of the further sleeping box. In other words, the fasteningapparatus may be configured to connect two sleeping boxes which arestacked one above the other, to one another. The fastening apparatusmay, in turn, have a latching fastener or quick-action fastener and beconfigured to interact with a fastening apparatus which is complementaryto it and which is provided in the area of an outer face of the ceilingof the casing of the further sleeping box.

The fastening apparatus of the sleeping box may also be configured toconnect the sleeping box to at least one further sleeping box in such away that a side wall of the casing of the sleeping box borders on a sidewall of the casing of the further sleeping box. The fastening apparatusof the sleeping box then additionally serves to connect sleeping boxeswhich are arranged side by side, and likewise preferably comprises alatching and/or quick-action fastener apparatus in order to permit quickand convenient connection of two sleeping boxes which are arranged sideby side.

In its interior space, the sleeping box is preferably equipped with areclining cushion which may be provided in the area of an inner face ofthe floor of the casing. A head cushion may also be provided which maybe fastened to the inner face of the floor of the casing or to thereclining cushion which is provided in the area of the inner face of thefloor of the casing. The sleeping box may also comprise at least onegripping recess which is formed in an inner face of the floor of thecasing and/or of the side wall of the casing, which inner face facestowards an interior space of the sleeping box. A number of grippingrecesses are preferably provided, which are formed in a row, one behindanother, in the inner face of the floor of the casing and/or of the sidewall of the casing which faces towards the interior space of thesleeping box. In one particularly preferred embodiment of the sleepingbox, there are provided, in the inner face of the floor of the casing,two rows of gripping recesses which each extend parallel to thelongitudinal axis of the casing in a manner adjacent to a side wall ofthe casing.

The sleeping box may also be equipped with at least one grip rail. Thegrip rail may extend parallel to the longitudinal axis of the casing.The grip rail may be fastened to an inner face of the ceiling of thecasing and/or of the side wall of the casing, which inner face facestowards an interior space of the sleeping box. One preferred embodimentof the sleeping box is equipped with two grip rails which are eachfastened to that inner face of the ceiling of the casing which facestowards the interior space of the sleeping box, and extend parallel tothe longitudinal axis of the casing in a manner adjacent to the sidewalls of the casing.

The sleeping box may also comprise at least one gripping element whichmay be fastened to the inner face of the ceiling of the casing whichfaces towards the interior space of the sleeping box, and/or to the griprail. The gripping element may be designed, for example, in the form ofa gripping loop and consist of a plastic material. If desired, thegripping element may be fastened so as to be displaceable parallel tothe longitudinal axis of the casing. For example the gripping elementmay be displaceable along a rail which may be attached to the inner faceof the ceiling of the casing which faces towards the interior space ofthe sleeping box. As an alternative to this, however, the grippingelement may also be fastened in a displaceable manner to a grip railwhich extends parallel to the longitudinal axis of the casing and ismounted on the inner face of the ceiling of the casing or of the sidewall of the casing. This makes it possible to dispense with additionalcomponents for mounting the gripping element. A sleeping box which isequipped with at least one gripping recess, at least one grip railand/or at least one gripping element not only offers simplified accessinto the sleeping box but also permits quicker, easier and thereforesafer evacuation of a person from the sleeping box.

In one preferred embodiment of the sleeping box, inner faces of thefloor of the casing, of the ceiling of the casing, of a rear wall of thecasing and/or of the side walls of the casing, which inner faces facetowards the interior space of the casing, are padded, at least incertain sections, by cushioning. This considerably reduces the risk ofinjury to a passenger occupying the sleeping box in the event of a crashor other action or incident. In addition, it is then possible, if theinner faces of the casing of the sleeping box are configured in a paddedmanner, to dispense with providing the sleeping box with a safety belt.

In addition, or as an alternative, to this, the sleeping box may beequipped with an inflatable airbag which is configured to deploy in thedirection of the interior space of the sleeping box if necessary. Theairbag ensures further cushioning of the inner faces of the casing andthus makes it possible to further reduce the risk of injury to apassenger accommodated in the sleeping box in the event of a crash orother action or incident. The airbag should be designed in such a waythat it permits, even in the deployed state, unimpeded evacuation of thepassenger from the sleeping box. This can be guaranteed if the airbag isso dimensioned that it forms, in the deploying state, a gas-filledcushion about 5 to 10 cm thick which extends over at least part of theinner faces of the casing of the sleeping box. The airbag may beprovided with a triggering mechanism which ensures deployment of theairbag when a predetermined acceleration acts upon the sleeping box. Theacceleration acting upon the sleeping box may, for example, be measuredby suitable acceleration sensors. As an alternative, or in addition, tothis, it is also conceivable to equip the airbag with a triggeringmechanism which can be activated by a signal which is inputted manuallyby a member of the cabin crew or the pilot. This activating signal maybe transmitted, for example, by a cabin communication system of theaircraft.

Finally, the interior space of the sleeping box is preferably designedso as to be devoid of edges and corners in order to protect a passengerwho is occupying the sleeping box from injuries. The casing of thesleeping box may comprise or consist of a plastic material or afibre-reinforced plastic material. The sleeping box then has a lowweight. The sleeping box is preferably so dimensioned and designed thatit withstands crash loads of 16G.

The sleeping box may be equipped with a personal service unit whichcomprises a plurality of service modules. For example, the personalservice unit of the sleeping box may comprise, in a manner similar to aconventional personal service unit which is arranged above the passengerseats in the passenger cabin of a commercial aircraft, an emergencyoxygen system, a loudspeaker, an individual air outlet and a lamp. Inaddition, the personal service unit of the sleeping box is preferablyequipped with a video camera which permits monitoring of the passengeraccommodated in the sleeping box in certain operating phases of theaircraft. For example, the video camera may be activated during taxiing,takeoff and/or landing of the aircraft in order to enable the flightattendants to monitor the passenger in the sleeping box.

The loudspeaker provided in the personal service unit may be used, inthe conventional manner, as an output unit of the cabin communicationsystem. In addition, however, the loudspeaker may also be used to outputan audible alarm signal to the passenger in the sleeping box, forexample to wake the passenger for the takeoff or landing of the aircraftor in an emergency situation. The outputting of the audible alarm signalvia the loudspeaker of the personal service unit of the sleeping box maybe initiated, for example manually, by a member of the cabin crew or thepilot. In addition, the loudspeaker of the personal service unit may beused as an output unit of an active noise-reduction system. All that isnecessary for this purpose is to connect the loudspeaker, preferably viathe interface element, to a primary noise-reduction system of theaircraft.

The service modules of the personal service unit are preferablyconnectable via an interface element to corresponding aircraft systemsfor the purpose of supplying the service modules. For example, theloudspeaker provided in the personal service unit may be connectable viathe interface to the cabin communication system. In a similar way, theindividual air outlet of the personal service unit may be connectablevia the interface to an individual air system of the aircraft. Theemergency oxygen system may preferably be connectable via the interfaceto a central oxygen system of the aircraft. Finally it is possible, viathe interface, to produce an electrical connection between electricalconsumers belonging to the personal service unit and a central currentsupply system of the aircraft. The interface make it possible to bringthe sleeping box into operation in a particularly simple manner since itpermits a “plug and play” connection between the sleeping box and theprimary supply systems of the aircraft. The interface is preferablyarranged in the area of an outer face of the rear wall of the casing andcan therefore be connected to the respective supply systems of theaircraft in a particularly simple and convenient manner when thesleeping box is installed in the passenger cabin.

The sleeping box may also comprise a display screen and/or an audiosystem which is connectable to an in-flight entertainment system of theaircraft. The connection between the display screen and/or audio systemand the in-flight entertainment system of the aircraft is preferablyproduced via the same interface element that also ensures a connectionof the service modules of the personal service unit to the correspondingsupply systems of the aircraft.

A rear wall of the casing of the sleeping box, which rear wall liesopposite the access aperture, may have a curvature which is adapted to acurvature of a passenger cabin wall at an intended site of installationof the sleeping box in the passenger cabin. The sleeping box can then bemounted in the passenger cabin with optimum utilization of theinstallation space available in the passenger cabin. In an area adjacentto the access aperture, on the other hand, the casing of the sleepingbox preferably has a square or rectangular cross-section.

A sleeping box arrangement comprises a plurality of the sleeping boxesdescribed above. The sleeping boxes are arranged side by side and/or oneabove another, and are preferably connected to one another via theabove-described fastening apparatuses or connecting apparatusesbelonging to the sleeping boxes. If the fastening apparatuses andconnecting apparatuses comprise, as described above, latching and/orquick-action fastener elements, particularly simple and rapidbuilding-up of the sleeping box arrangement from a plurality of sleepingboxes is possible. A sleeping box arrangement which comprises aplurality of sleeping boxes arranged side by side and/or one aboveanother forms a kind of honeycomb system which is distinguished by highload stability. This makes possible a lightweight design of the sleepingbox arrangement.

The sleeping box arrangement may comprise at least one foothold and/orat least one handhold which is/are attached, in the area of the accessaperture, to an edge of the floor of the casing, of the ceiling of thecasing and/or of a side wall of the casing of at least one sleeping box.Such a configuration of the sleeping box arrangement permits convenientaccess, even into sleeping boxes belonging to the sleeping boxarrangement which are situated high up.

Within the sleeping box arrangement, the sleeping boxes may be arrangedin three rows, one above another. If the casing of each sleeping boxbelonging to the sleeping box arrangement has a cross-section of about800 mm×800 mm in the area of the access aperture, a sleeping boxarrangement with six sleeping boxes can then be installed in the economyclass of the passenger cabin of the aircraft instead of three rows ofseats. In the lower two rows of sleeping boxes belonging to the sleepingbox arrangement, the side walls of the casing of sleeping boxes whichare positioned one above another are preferably arranged so as to becoplanar in relation to one another. In contrast to this, the side wallsof the casing of sleeping boxes which are positioned one above anotherin the upper rows are preferably arranged so as to be offset in relationto one another. An offset arrangement of the sleeping boxes in the thirdrow of the sleeping box arrangement increases the stiffness of thehoneycomb-like sleeping box arrangement. In addition, the sleeping boxesin the third row of the sleeping box arrangement are more convenientlyand easily accessible if they are positioned so as to be offset inrelation to the sleeping boxes located underneath them.

In a sleeping box arrangement that comprises a number of sleeping boxes,each sleeping box may, as described above, be equipped with an interfaceelement which connects service modules of a personal service unit whichare provided in the sleeping box and/or output units of an in-flightentertainment system, to the corresponding primary aircraft systems. Asan alternative to this, however, it is also conceivable to provide acentral interface element for connecting the complete sleeping boxarrangement to the primary aircraft systems. The sleeping boxarrangement is then equipped with corresponding distributor systemswhich ensure the connection of the individual sleeping boxes to thecentral interface element, and thereby to the primary aircraft systems.

Within the sleeping box arrangement, sleeping boxes which are arrangedside by side in a row may have the same length. In contrast to this,sleeping boxes belonging to the sleeping box arrangement which arearranged one above another preferably have different lengths, the lengthof the sleeping boxes being, in particular, greater, the lower down thesleeping boxes are arranged within the sleeping box arrangement. As aresult of such a configuration of the sleeping box arrangement, accountis taken of the curved contour of the side wall of the passenger cabinat an intended site of installation of the sleeping box arrangement inthe passenger cabin, and at the same time, optimum utilization of theinstallation space available is guaranteed.

An aircraft area comprises an aisle which extends along a longitudinalaxis of a passenger cabin. The aircraft area is also equipped with atleast one door aisle which extends perpendicularly to the longitudinalaxis of the passenger cabin and connects the aisle to at least oneaircraft door. Within the aircraft area, aircraft doors are preferablylocated at two mutually opposite ends of the door aisle. Also providedwithin the aircraft area is a sleeping box area in which at least oneabove-described sleeping box or at least one above-described sleepingbox arrangement is arranged in such a way that the longitudinal axis ofthe casing of the sleeping box(es) extends perpendicularly to thelongitudinal axis of the passenger cabin, and the access aperture of thecasing of the sleeping box(es) borders on the aisle. The aircraft areaconsequently comprises a sleeping box area which is integrated into thepassenger cabin and in which at least one sleeping box, which isconveniently accessible from the aisle of the aircraft area, isarranged.

The sleeping box area is preferably constituted by an area of thepassenger cabin which is devoid of passenger seats and which extendsover a predetermined length along the longitudinal axis of the passengercabin. The predetermined length of the sleeping box area along thelongitudinal axis of the passenger cabin may vary, according torequirements. For example, the sleeping box area may be enlarged ordiminished in the context of an occupancy-initiated or seasonalreconfiguration of the passenger cabin of the aircraft. If the sleepingbox area is constituted by an area of the passenger cabin which isdevoid of passenger seats, it is guaranteed that, in an emergency,evacuation of the passengers from the sleeping boxes set up within thesleeping box area is not hindered by passengers who are sitting onpassenger seats installed in the passenger cabin. Conversely, theevacuation of the passengers who are obliged to leave their passengerseats which are installed in rows in the passenger cabin is notdisrupted by the passengers who are leaving the sleeping boxes. It isthereby possible to develop a separate evacuation scenario for thesleeping box area.

The sleeping box area is preferably connected, via at least one escaperoute which is not restricted by passenger seats, to at least oneaircraft door. This guarantees an evacuation sequence which is furtheroptimised, both for passengers who are occupying sleeping boxesinstalled in the sleeping box area of the aircraft area, and forpassengers who are sitting on passenger seats.

The sleeping box area within the aircraft area preferably borders on thedoor aisle. This permits unimpeded access to the aircraft doors in theevent of an evacuation of the sleeping box area. The door aisle adjacentto the sleeping box area is, in particular, a door aisle which isadjacent, on a side that lies opposite the sleeping box area, to an areaof the aircraft devoid of passenger seats, and is consequently notfrequented, in the event of an evacuation of the passenger cabin, bypassengers who are sitting on passenger seats installed in the passengercabin. The door aisle is therefore exclusively available, in anemergency, for an evacuation of the passengers from the sleeping boxarea.

The aircraft area preferably also comprises a freight compartment areawhich is connected to the passenger cabin via an access. There may beaccommodated within the freight compartment area at least one freightcontainer, in the interior space of which there is provided at least onesleeping box which is suitable for accommodating a person located in areclining position parallel to a longitudinal axis of the sleeping box,and which has an access aperture in the area of a front side whichextends perpendicularly to the longitudinal axis of the sleeping box.The freight container in question is preferably one which corresponds,as regards its shape and dimensioning, to a conventional freightcontainer and which is consequently suitable for being accommodated inthe freight area of the aircraft area.

The sleeping box provided within the freight container may, as describedabove, be equipped with at least one gripping recess, at least one griprail and/or at least one gripping element. A padded configuration of thesleeping box and/or the equipping of the sleeping box with an airbag isalso conceivable. The sleeping box may likewise comprise a personalservice unit with a plurality of service modules, a display screenand/or an audio system. These systems can be connected to correspondingsupply systems of the aircraft, preferably via a corresponding interfaceelement which may be arranged in the area of an outer face of thefreight container.

The freight container within which the at least one sleeping box isaccommodated, is preferably of gastight design in order to permit theuse of fire-extinguishing means within the freight compartment area inthe event of a fire. A number of freight containers, within the interiorspace of which at least one sleeping box is provided, are preferablyconnected to one another by an aisle. An aisle of this kind, which isprovided between mutually opposite or mutually adjacent sleeping boxes,should likewise be of correspondingly gastight design. If mutuallyadjacent freight containers are connected to one another by an aisle,passengers can enter a first freight container, which lies closest tothe passenger cabin, and then move through the aisle to the adjacentfreight containers. The aisle may be closable at one end or at both endsby a door. The freight containers, which are arranged in a row, may alsobe provided with corresponding doors.

The freight compartment area may be loaded, in a utilization-dependentmanner, with freight containers, within the interior space of which atleast one sleeping box is provided, and with conventional freightcontainers. When the freight compartment area is being loaded, thefreight containers within the interior space of which at least onesleeping box is provided, are preferably brought into the freightcompartment area first so that, when the freight compartment area iscompletely loaded, they are then located in a rear area of the freightcompartment area, that is to say one which is furthest away from afreight compartment door. This section of the freight compartment areamay be connected, for example via a staircase or a door, to thepassenger cabin, so that unimpeded access into the freight compartmentarea from the passenger cabin is possible. A section of the freightcompartment area which lies closer to the freight compartment door may,on the other hand, be loaded with conventional freight containers, sothat the loading and unloading of these containers is not hindered bythe freight containers which are provided, in their interior space, withat least one sleeping box.

DETAILED DESCRIPTION

FIGS. 1a to 1e show a first embodiment of a sleeping box arrangement 100which is suitable for installation in an aircraft. The sleeping boxarrangement 100 comprises a plurality of sleeping boxes 10 which arearranged in three rows, one above another. The sleeping box arrangement100 has a honeycomb-like structure which is distinguished by highmechanical stability and load-resistance. As a result of this, thesleeping box arrangement 100 can be of comparatively lightweight design.In any case, each sleeping box 10 belonging to the sleeping boxarrangement 100 should withstand an impact load of 16G.

Each sleeping box 10 has a casing 12 which is suitable for accommodatinga person who is located in a reclining position parallel to alongitudinal axis L_(G) of the casing 12. In the area of a front side,which extends perpendicularly to the longitudinal axis L_(G) of thecasing 12, each sleeping box 10 has an access aperture 14. Each sleepingbox 10 is provided with a fastening apparatus 16 which is configured tofasten the sleeping box 10 within a passenger cabin 18 of the aircraft,see FIG. 3.

The casing 12 of each sleeping box 10 comprises a floor 22 of thecasing, a ceiling 24 of the casing which lies opposite the floor 22 ofthe casing, two mutually opposite side walls 26, 28 of the casing and arear wall 30 of the casing. In the area of the access aperture 14, thecasing 12 of each sleeping box 10 has a square cross-section anddimensions of 800 mm×800 mm, in order to facilitate access into aninterior space of the sleeping box 10. The rear wall 30 of the casing,however, is of curved design, see in particular FIGS. 1b, 1c, 1d, 1e , 3and 4, the curvature of the rear wall 30 of the casing being adapted toa curvature of a wall 32 of the passenger cabin at an intended site ofinstallation of the sleeping box arrangement 100 and consequently ofeach sleeping box 10 within the passenger cabin 18. As a result of this,optimum utilization of the installation space available within thepassenger cabin 18 is guaranteed when the sleeping box arrangement 100is installed in the passenger cabin 18.

The fastening apparatus 16 is configured to fasten the sleeping box 10within the passenger cabin 18 in such a way that the longitudinal axisL_(G) of the casing 12 of the sleeping box 10 extends perpendicularly toa longitudinal axis L_(P) of the passenger cabin 18, the access aperture14 of the casing 12 bordering on an aisle 33 which is present in thepassenger cabin 18. The sleeping boxes 10 of the sleeping boxarrangement 100 are consequently conveniently accessible to passengersfrom the aisle 33. In addition, the orientation of the sleeping boxes 10relative to the longitudinal axis L_(P) of the passenger cabin 18guarantees that the persons occupying sleeping boxes 10 belonging to thesleeping box arrangement 100 lie perpendicularly to the longitudinalaxis L_(P) of the passenger cabin 18 and consequently perpendicularly tothe direction of flight of the aircraft. In the event of a crash orother action or incident, persons who are lying in the sleeping boxes 10are consequently pressed flat against one of the side walls 26, 28 ofthe casing. Under these circumstances, the load acting upon the person'sbody is distributed uniformly over the entire body, as a result of whichthe risk of injury can be minimised. The sleeping boxes 10 of thesleeping box arrangement 100 may consequently remain occupied evenduring taxiing, takeoff and landing of the aircraft, so that it is notnecessary to provide additional seats in the passenger cabin 18 forpassengers who are occupying the sleeping boxes 10.

As an alternative to this, however, scenarios for using the sleeping boxarrangement 100 are also conceivable in which passengers book both aseat and a place in one of the sleeping boxes 10. These passengers havethe possibility of occupying their seat or their sleeping box 10,according to their choice. In particular, they are able to go to theirsleeping box 10 in order to sleep, whereas meals and beverages can beconsumed while sitting down. A booking scenario can also be imagined inwhich two passengers share a seat and a sleeping box 10 and occupy theseat and the sleeping box 10 alternately.

The design of the fastening apparatus 16 of each sleeping box 10, whichfastens the sleeping box 10 in the desired position within the passengercabin 18, is adapted to the position of the sleeping box 10 within thesleeping box arrangement 100. Sleeping boxes 10 which are arranged inthe bottommost row of the sleeping box arrangement 100 each have afastening apparatus 16 which is configured to fasten the sleeping box 10to seat rails 36 provided in a floor 34 of the passenger cabin 18. Ascan be seen particularly from FIGS. 1b and 3, each of the sleeping boxes10 located in the bottommost row of the sleeping box arrangement 100 isprovided with five latching or quick-action fastener elements 38 whichare set up for the purpose of latching engagement, in each case, withone of the seat rails 36 which are let into the floor 34 of thepassenger cabin 18 and extend parallel to the longitudinal axis L_(P) ofthe passenger cabin 18. The quick-action fastener elements 38 areprovided in the area of an outer face of the floor 22 of the casing andpermit, not only particularly quick and easy mounting of the sleepingbox arrangement 100 within the passenger cabin 18, but also, for examplein the event of a reconfiguration of the passenger cabin 18, easy andconvenient repositioning of the sleeping box arrangement 100.

The fastening apparatus of the sleeping boxes 10 which are arranged inthe bottommost row of the sleeping box arrangement 100 is alsoconfigured to connect the sleeping box 10 to at least one other sleepingbox 10 in such a way that a side wall 26, 28 of the casing of thesleeping box 10 borders on a side wall 26, 28 of the casing of the othersleeping box 10. For this purpose, the fastening apparatus 16 isprovided with quick-action fastener elements 39 which are illustrated inFIG. 2 and which are each attached to connecting edges between the sidewalls 26, 28 of the casing and the floors 22 of the casing of thesleeping boxes 10.

In contrast to this, the sleeping boxes 10 which are positioned in themiddle row of the sleeping box arrangement 100 are each provided with afastening apparatus 16 which serves to fasten the sleeping box 10 toanother sleeping box 10, which is located underneath it, belonging tothe sleeping box arrangement 100, in such a way that a floor 22 of thecasing of the upper sleeping box 10 borders on a ceiling 24 of thecasing of a sleeping box 10 which is located underneath it. Thisfastening apparatus 16 comprises quick-action fastener elements 40 whichare attached to connecting edges between the side walls 26, 28 of thecasing and the floors 22 of the casing or ceilings 24 of the casing ofthe sleeping boxes 10 and which interact with complementary quick-actionfastener elements 41 which are attached to connecting edges between theside walls 26, 28 of the casing and the ceilings 24 of the casing of thesleeping boxes 10 in the bottommost row of the sleeping box arrangement100. The quick-action fastener elements 40 of the sleeping boxes 10 inthe middle row also serve for connecting sleeping boxes 10 which arelaterally adjacent to one another in the middle row. In the same way,the quick-action fastener elements 41 of the sleeping boxes 10 in thebottommost row also fulfil the double function of, on the one hand,ensuring the fastening of a sleeping box 10 in the middle row to asleeping box 10 in the bottommost row and, on the other hand, connectingtwo sleeping boxes 10 in the bottommost row, which are laterallyadjacent to one another, to one another. The fastening apparatus 16 ofthe sleeping boxes 10 in the middle row of the sleeping box arrangement100 also comprises quick-action fastener elements 42 which are attachedto connecting edges between the side walls 26, 28 of the casing and theceilings 24 of the casing of the sleeping boxes 10 in the middle row ofthe sleeping box arrangement 100. These quick-action fastener elements42 serve to connect sleeping boxes 10 in the middle row which arelaterally adjacent to one another.

Finally, the sleeping boxes 10 which are positioned in the uppermost rowof the sleeping box arrangement 100 also each comprise a fasteningapparatus 16 which serves to fasten the sleeping box 10 to anothersleeping box 10, which is located underneath it, belonging to thesleeping box arrangement 100 in such a way that a floor 22 of the casingof the upper sleeping box 10 borders on a ceiling 24 of the casing of asleeping box 10 which is located underneath it. This fastening apparatus16 comprises quick-action fastener elements 43 which are attached in thearea of the floors 22 of the casing of the sleeping boxes 10 and whichinteract with complementary quick-action fastener elements 44 which areattached in the area of the ceilings 24 of the casing of the sleepingboxes 10 in the middle row of the sleeping box arrangement 100. Thequick-action fastener elements 43 of the sleeping boxes 10 in theuppermost row also serve to connect sleeping boxes 10 in the uppermostrow which are laterally adjacent to one another. The fastening apparatus16 of the sleeping boxes 10 in the uppermost row of the sleeping boxarrangement 100 also comprises quick-action fastener elements 45 whichare attached to connecting edges between the side walls 26, 28 of thecasing and the ceilings 24 of the casing of the sleeping boxes 10 in theuppermost row of the sleeping box arrangement 100. These quick-actionfastener elements 45 serve to connect sleeping boxes 10 in the uppermostrow which are laterally adjacent to one another.

The interior space of each sleeping box 10 of the sleeping boxarrangement 100 is equipped with a reclining cushion 46, which isprovided in the area of an inner face of the floor 22 of the casing, andalso with a head cushion 48. Inner faces of the ceiling 24 of thecasing, of the side walls 26, 28 of the casing and of the rear wall 30of the casing, which inner faces face towards the interior space of thesleeping box 10, are also padded by cushioning 49, as a result of whichthe risk of injury, in the event of a crash or other action or incident,to a person lying in the sleeping box 10 can be minimised. It istherefore possible to dispense with making a safety belt availablewithin the sleeping boxes 10.

In order to further improve the safety, each sleeping box 10 is equippedwith an airbag 50 which is indicated merely diagrammatically in FIG. 1a. The inflatable airbag 50 can be activated by a triggering mechanism,of which no further details are indicated, and is deployed in thedirection of the interior space of the sleeping box 10 when thetriggering mechanism is activated. However the airbag 50 is sodimensioned that it does not excessively restrict the volume of theinterior space of the sleeping boxes 10. On the contrary, the airbag 50merely forms a gas-filled cushion about 5 to 10 cm thick which extendsover the inner faces of the ceiling 24 of the casing, of the side walls26, 28 of the casing and of the rear wall 30 of the casing. Finally, theinterior space of each sleeping box 10 is devoid of edges and corners.

As can best be seen in FIG. 4, each sleeping box 10 of the sleeping boxarrangement 100 is provided with a plurality of gripping recesses 52which are arranged, one behind another, along the longitudinal axisL_(G) of the casing 12. The gripping recesses 52 are arranged in tworows and are let, in a manner adjacent to the side walls 26, 28 of thecasing, into an inner face of the floor 22 of the casing, which innerface faces towards the interior space within the sleeping box 10. Eachsleeping box 10 is also equipped with two grip rails 54 which arefastened, in a manner adjacent to the side walls 26, 28 of the casing,to an inner face of the ceiling 24 of the casing that faces towards theinterior space of the sleeping box 10, and extend parallel to thelongitudinal axis L_(G) of the casing 12. Finally, two gripping elements56, which are constructed in the form of a loop and are produced from aflexible plastic material, are provided in each of the sleeping boxes10. The gripping elements 56 are mounted on an inner face of the ceiling24 of the casing. The gripping recesses 52, grip rails 54 and grippingelements 56 make it easier to climb into the sleeping box, and inparticular to climb out of the sleeping box 10, and can consequentlyconsiderably accelerate the evacuation of persons from the sleepingboxes 10.

As can best be seen in FIGS. 1a and 2, the sleeping box arrangement 100is also equipped with a plurality of rungs 58 which are attached, oneabove another, to an edge of the side walls 26, 28 of the casing andalso of the floors 22 of the casing and of the ceilings 24 of the casingin the area of the access apertures 14 of the sleeping boxes 10. Accessinto the sleeping boxes 10 located at the top in the sleeping boxarrangement 100 is made possible for passengers via the rungs 58. Inorder to make it easier to climb into the sleeping boxes 10 in theuppermost row of the sleeping box arrangement 100, each sleeping box 10in the uppermost row of the sleeping box arrangement 100 is alsoprovided with a handhold 60 which is attached to an edge of the sidewalls 26, 28 of the casing of the sleeping boxes 10 in the area of theaccess aperture 14.

Within the sleeping box arrangement 100, sleeping boxes 10 which arearranged side by side in a row each have the same length. Howeversleeping boxes 10 which are arranged one above another have differentlengths, the length of the sleeping boxes 10 in the sleeping boxarrangement 100 being greater, the lower down the sleeping boxes 10 arearranged within the sleeping box arrangement 100, see in particularFIGS. 3 and 4. As a result of this configuration of the sleeping boxarrangement 100, account is taken of the curved contour of the wall 32of the passenger cabin at the desired site of installation of thesleeping box arrangement 100 within the passenger cabin 18.

The sleeping boxes 10 are also positioned, relative to one another,within the sleeping box arrangement 100 in such a way that side walls26, 28 of the casing of sleeping boxes 10 which are positioned one aboveanother in the lower two rows of sleeping boxes of the sleeping boxarrangement 100 are arranged so as to be coplanar in relation to oneanother. In contrast to this, the side walls 26, 28 of the casing ofsleeping boxes 10 which are positioned one above another in the uppertwo rows of sleeping boxes of the sleeping box arrangement 100 arearranged so as to be offset in relation to one another. In other words,the uppermost row of sleeping boxes is positioned so as to be offsetrelative to the lower two rows of sleeping boxes. As a result of thisconfiguration of the sleeping box arrangement 100, the stability of thehoneycomb-like sleeping box arrangement 100 is improved. It is also madeeasier to climb into the sleeping boxes 10 in the upper rows of thesleeping box arrangement 100.

As can best be seen in FIGS. 4, 5 a and 5 b, each sleeping box 10 of thesleeping box arrangement 100 is also equipped with a personal serviceunit 62. Each personal service unit 62 comprises a plurality of servicemodules which, in the embodiment of a personal service unit 62illustrated in FIG. 5a , is configured in the form of an emergencyoxygen system 64, a loudspeaker 66, an individual air outlet 68, a lamp70 and a video camera 72. The service modules 64, 66, 68, 70, 72 can beconnected, via an interface element 74, to corresponding aircraftsystems for supplying the service modules 64, 66, 68, 70, 72. Inparticular, the emergency oxygen system 64 is connected, via theinterface element 74, to a central oxygen supply system of the aircraft.The loudspeaker 66 is connected to a cabin communication system and alsoto a noise-reduction system of the aircraft. In addition to conventionalannouncements, it is also possible to output audio signals via theloudspeaker 66, for example in order to wake a passenger lying in thesleeping box 10 for the takeoff or landing of the aircraft or in anemergency. The outputting of such an audio signal may be initiatedmanually by the crew members or the pilot. The loudspeaker may also beused as an output unit of an active noise-reduction system.

The individual air outlet 68 is connected, via the interface element 74,to a central individual air supply system of the aircraft, while thelamp 70 is supplied with electrical energy, via the interface element74, by a central energy supply system of the aircraft. The video camera72, too, is connected to the electrical supply system of the aircraftvia the interface element 74. Moreover, the video camera 72 transmitsvideo signals, via the interface element 74, to a central monitoringsystem of the aircraft which enables the cabin crew to monitorpassengers lying in the sleeping boxes 10, particularly during thetakeoff and landing of the aircraft and also when taxiing. Finally, eachsleeping box 10 is equipped with a display screen 76. The display screen76 has an integrated audio system 78 and can be connected, via theinterface element 74, to an in-flight entertainment system of theaircraft.

In principle, each sleeping box 10 of the sleeping box arrangement 100may be connected to the central supply systems of the aircraft via aseparate interface element 74. As an alternative to this, however, aconfiguration of the sleeping box arrangement 100 with just one centralinterface element, which ensures the connection of all the sleepingboxes 10 of the sleeping box arrangement 100 to the central supplysystems of the aircraft, is also conceivable.

The sleeping box arrangement 100 illustrated in FIGS. 6 and 7 differsfrom the configuration of the sleeping box arrangement 100 illustratedin FIGS. 1 to 5 through the fact that the sleeping boxes 10 in theuppermost row of the sleeping box arrangement 100 are not arranged so asto be offset in relation to the sleeping boxes 10 in the rows lyingunderneath them. As a result of this, the quick-action fastener elements43 of the fastening apparatus 16 of the sleeping boxes 10 in theuppermost row of the sleeping box arrangement 100 interact with thequick-action fastener elements 42 of the fastening apparatus 16 of thesleeping boxes 10 in the middle row of the sleeping box arrangement 100,in order to fasten the sleeping boxes 10 in the uppermost row of thesleeping box arrangement 100 on the sleeping boxes 10 in the middle rowof the sleeping box arrangement 100. Both the quick-action fastenerelements 43 and the quick-action fastener elements 42 then also fulfilthe function of connecting two sleeping boxes 10 which are laterallyadjacent to one another, to one another. In other respects, the sleepingbox arrangement 100 corresponds, as regards its structural configurationand its functionality, to the sleeping box arrangement 100 shown inFIGS. 1 to 5.

FIGS. 8 to 10 show various forms of embodiment of an aircraft area 200within which a plurality of sleeping box arrangements 100, as shown inFIGS. 1 to 7, are set up. The aircraft area 200 forms part of thepassenger cabin 18 of the aircraft and has an aisle 33 which extendsalong the longitudinal axis L_(P) of the passenger cabin 18. Alsoprovided within the aircraft area 200 is a door aisle 80 which extendsperpendicularly to the longitudinal axis L_(P) of the passenger cabin 18and connects the aisle 33 to at least one aircraft door 82. In the formsof embodiment of an aircraft area 200 shown in FIGS. 8 to 10, the dooraisle 80 connects the aisle 33 to each of two mutually opposite aircraftdoors 82.

Provided within the aircraft area 200 is a passenger seating area 85equipped with passenger seats 84, and also a sleeping box area 86. Anumber of sleeping box arrangements 100 are installed in the sleepingbox area 86 in such a way that the longitudinal axis L_(G) of the casing12 of the sleeping boxes 10 of the sleeping box arrangements 100 extendsperpendicularly to the longitudinal axis L_(P) of the passenger cabin 18in each case. The access aperture 14 of the casing 12 of all thesleeping boxes 10 borders on the aisle 33, so that the sleeping boxes 10are conveniently accessible to passengers from the aisle 33. In contrastto the passenger seating area 85 equipped with seats, the sleeping boxarea 86 is equipped with just one aisle 33 which is flanked on bothsides by sleeping box arrangements 100. On the other hand, the passengerseating area 85 equipped with seats has two main aisles 87 a, 87 b whichextend along the longitudinal axis L_(P) of the passenger cabin 18.

The sleeping box area 86 is constituted by an area of the passengercabin 18 which extends over a desired length of the longitudinal axisL_(P) of the passenger cabin 18, but which is not equipped withpassenger seats 84 and is consequently devoid of passenger seats. Inaddition, the sleeping box area 86 in the arrangement according to FIG.8 is connected to the aircraft doors 82, as is indicated by the arrowsin FIG. 8, via escape routes F1, F2 which are not restricted bypassenger seats 84, that is to say do not border on the passengerseating area 85. This permits quick and undisrupted evacuation of thesleeping box area 86 in an emergency. In particular, the sleeping boxarea 86 borders on the door aisle 80, so that passengers who are obligedto leave the sleeping boxes 10 within the sleeping box area 86 asquickly as possible in an emergency, can get to the aircraft doors 82unhindered by passengers who are accommodated in the passenger seatingarea 85.

In the case of the aircraft area 200 illustrated in FIG. 8, the sleepingbox area 86 is located in a front area of the passenger cabin 18, viewedin the direction of flight. In contrast to this, the sleeping box area86 is arranged, in the case of the aircraft area 200 shown in FIG. 9, ina tail area of the aircraft. In the case of the aircraft area 200according to FIG. 9, the sleeping box area 86 is divided up into twopartial areas 86 a, 86 b which are located respectively in front of, andbehind, the door aisle 80, viewed in the direction of flight of theaircraft. However, the two partial regions 86 a, 86 b of the sleepingbox area 86 directly border on the door aisle 80 and are thereforeconnected to the aircraft doors 82 via escape routes F1, F2, F3, F4which are each unrestricted by passenger seats 84.

The aircraft area 200 shown in FIG. 10 differs from the aircraft area200 according to FIG. 9 through the fact that the sleeping box area 86,that is to say the partial sleeping box area 86 a, extends further alongthe longitudinal axis L_(P) of the passenger cabin 18 in the directionof a front area of the aircraft, so that the sleeping box area 86, thatis to say the partial sleeping box area 86 a, borders not only on thedoor aisle 80 located in a tail area of the aircraft but also on anotherdoor aisle 88 located in a central area of the aircraft. As a result ofthis, there are available to passengers accommodated in the sleepingboxes 10 six escape routes F1, F2, F3, F4, F5, F6, via which thepassengers can get to the aircraft doors 82 or to other aircraft doors90 without coming into contact with the passenger seating area 85.

As can be seen from FIG. 11, the aircraft area 200, as shown in FIGS. 8to 10, may be supplemented by a freight compartment area 92 which isaccommodated in a lower deck of the aircraft. As FIG. 12 shows, thefreight compartment area 92 is connected to the passenger cabin 18 inthe upper deck via an access 96 which may be designed in the form of astaircase or a lift. Accommodated within the freight compartment area 92is at least one freight container 98, in the interior space of which atleast one sleeping box 10 is provided. The freight container 98 may, forexample, be configured in such a way that there is room for sevensleeping boxes 10 in its interior space. Each sleeping box 10 issuitable for accommodating one person, who is located in a recliningposition parallel to a longitudinal axis L_(S) of the sleeping box 10.The sleeping box 10 also has an access aperture 14 in the area of afront side which extends perpendicularly to the longitudinal axis L_(S)of the sleeping box 10. The freight container 98 corresponds, as regardsits shape and dimensioning, to a conventional freight container 100 andis consequently, just like a conventional freight container 100,suitable for being accommodated within the freight compartment area 92.

The sleeping boxes 10 provided in the freight container 98 may beequipped as described above. The freight container 98 within which thesleeping boxes 10 are accommodated is also of gastight design in orderto permit the use of fire-extinguishing means within the freightcompartment area 92 in the event of a fire. An aisle area 102 which isprovided between mutually opposite sleeping boxes 10 within the freightcontainer 98 is accordingly also of gastight design.

The freight compartment area 92 may be loaded, in autilization-dependent manner, with freight containers 98, in theinterior space of which sleeping boxes 10 are provided, and withconventional freight containers 100. As can be seen from FIG. 12, thefreight containers 98, in the interior space of which sleeping boxes 10are provided, are accommodated, viewed in a direction of loading L inwhich freight containers 98, 100 are brought into the freightcompartment 94, in a rear part of the freight compartment area 92 whichdirectly borders on the access 96 into the passenger cabin 18 in theupper deck. When the freight compartment area 92 is loaded, the freightcontainers 98 equipped with sleeping boxes 10 are consequently loaded infirst, before the freight compartment area 92 is finally loaded withconventional freight containers 100. This guarantees unimpeded loadingand unloading of the conventional freight containers 100.
